Welcome to ASDM

Welcome to ASDM, a browser-based, Java applet used to configure and monitor the software on security appliances. ASDM is loaded from the security appliance, then used to configure, monitor, and manage the device.

Important Notes

•CLI Command Support—With a few exceptions, almost all CLI commands are fully supported by ASDM. For a list of commands ASDM does not support, see Unsupported Commands.

•Multiple ASDM Sessions—ASDM allows multiple PCs or workstations to each have one browser session open with the same security appliance software. A single security appliance can support up to 5 concurrent ASDM sessions in single, routed mode. Only one session per browser per PC or workstation is supported for a particular security appliance. In multiple context mode, five concurrent ASDM sessions are supported per context, up to a limit of 32 connections total per security appliance.

•Security Appliance Release—This release of ASDM requires Version 7.1 and does not run with earlier security appliance releases.

•Caveats—Use the Bug Toolkit on cisco.com to view current caveat information. You can access Bug Toolkit at:

Features Introduced in the 5.2(3) Release

See the following topics for more information about the new features in the 5.2(3) release:

•Multiple ASDM Session Support—ASDM allows multiple PCs or workstations to each have one browser session open with the same adaptive security appliance software. A single adaptive security appliance can support up to five concurrent ASDM sessions in single, routed mode. Only one session per browser per PC or workstation is supported for a specified adaptive security appliance. In multiple context mode, five concurrent ASDM sessions are supported per context, up to a maximum of 32 total connections for each adaptive security appliance.

•Added support for new ESMTP parameter allow-tls [action log] in the ESMTP policy map. When parameter is on, traffic on an ESMTP session will not be inspected after the exchange of client's STARTTLS command and server's 220 reply code. To implement this parameter, see Configuration Global Objects > Inspect Maps > ESMTP. After map is inspected or edited, select the entry and click Advanced View to access the ESMTP policy map parameter.

•Added the inspect waas command to support WAAS inspection. See Service Policy Rule > Protocol Inspection.

•Added new command, smartcard-removal-disconnect [enable | disable] in group policy configuration mode, to specify that tunnels stay connected when the SmartCard is removed. Currently, the default behavior is that tunnels are disconnected when a SmartCard is removed.

•Increased VLAN range for the ASA 5505--The ASA 5505 adaptive security appliance now supports VLAN IDs between 1 and 4090. Originally, only VLAN IDs between 1 and 1001 were supported.

Features Introduced in the 5.2(4) Release

See the following topics for more information about the new features in the 5.2(4) release:

•Network Objects-- You can now add true network objects that you can use in firewall rules. Objects can be named, and when you edit an object, the change is inherited wherever the object is used. Also, when you create a rule, the networks that you specify in the rule are automatically added to the network object list so you can reuse them elsewhere. You can name and edit these automatic entries as well. See Configuration > Objects > Network Objects/Groups.

•QoS Traffic Shaping--If you have a device that transmits packets at a high speed, such as a security appliance with Fast Ethernet, and it is connected to a low speed device such as a cable modem, then the cable modem is a bottleneck at which packets are frequently dropped. To manage networks with differing line speeds, you can configure the security appliance to transmit packets at a fixed slower rate. See the Configuration > Security Policy > Service Policy Rules pane, and then add or edit a rule to access the QoS tab. Note that the only traffic class supported for traffic shaping is class-default, which matches all traffic.

See the crypto ipsec security-association replay command, which lets you configure the IPSec anti-replay window size. One side-effect of priority queueing is packet re-ordering. For IPSec packets, out-of-order packets that are not within the anti-replay window generate warning syslog messages. These warnings become false alarms in the case of priority queueing. This new command avoids possible false alarms.

•Timeout for SIP provisional media--You can now configure the timeout for SIP provisional media on the Configuration > Properties > Timeouts pane.

•Rate and burst limit sizes for ICMP messages can now be adjusted from the Configuration > Properties > ICMP Rules pane.

•TCP normalization enhancements--You can now configure TCP normalization actions for certain packet types. Previously, the default actions for these kinds of packets was to drop the packet. Now you can set the TCP normalizer to allow the packets.

–TCP invalid ACK check

–TCP packet sequence past window check

–TCP SYN-ACK with data check

You can also set the TCP out-of-order packet buffer timeout. Previously, the timeout was 4 seconds. You can now set the timeout to another value.The default action for packets that exceed MSS has changed from drop to allow. See the Configuration > Global Objects > TCP Maps pane. The following non-configurable actions have changed from drop to clear for these packet types:

–Bad option length in TCP

–TCP Window scale on non-SYN

–Bad TCP window scale value

–Bad TCP SACK ALLOW option

Unsupported Commands

ASDM supports almost all commands available for the security appliance, but some commands in an existing configuration are ignored by ASDM. Most of these commands can remain in your configuration; see Show Commands Ignored by ASDM on Device for the ignored commands in your configuration.

In the case of the alias command, ASDM enters into Monitor-only mode until you remove the command from your configuration.

Ignored and View-Only Commands

The following table lists commands that ASDM supports in the configuration when added by the CLI, but that cannot be added or edited in ASDM. If ASDM ignores the command, it does not appear in the ASDM GUI at all. If it is view-only, then the command appears in the GUI, but you cannot edit it.

Effects of Unsupported Commands

•If ASDM loads an existing running configuration and finds IPv6-related commands, ASDM displays a dialog box informing you that it does not support IPv6. You cannot configure any IPv6 commands in ASDM, but all other configuration is available.

•If ASDM loads an existing running configuration and finds other unsupported commands, ASDM operation is unaffected. To view the unsupported commands, see Options > Show Commands Ignored by ASDM on Device.

–The CLI tool (Tools > Command Line Interface), which lets you use the CLI commands.

To exit Monitor-only mode, use the CLI tool or access the security appliance console, and remove the alias command. You can use outside NAT instead of the alias command. See the Cisco ASA 5500 Series Command Reference for more information.

Note You might also be in Monitor-only mode becauseyour user account privilege level, indicated in the status bar at the bottom of the main ASDM window, was set up as less than or equal to 3 by your system administrator, which allows Monitor-only mode. For more information, see Configuration > Properties > Device Administration > User Accounts and Configuration > Device Access > AAA Access.

Other CLI Limitations

ASDM does not support discontinuous subnet masks such as 255.255.0.255. For example, you cannot use the following:

ip address inside 192.168.2.1 255.255.0.255

About the ASDM Window

The ASDM Window is designed to provide easy access to the many features that the security appliance supports. The ASDM Window includes the following:

•Toolbar—Lets you navigate ASDM. From the toolbar you can access the home page, configuration, and monitoring panels. You can also search for features, save the configuration, get help and navigate back and forth between panels. The Home, Configuration, and Monitoring buttons each open a panel with a variety of useful tools. The home page offers much information at a glance. Configuration and monitoring offer a useful category tree along the left side of the frame, for access to more detailed configuration or monitoring information.

•Status Bar—Shows the time, connection status, user, and privilege level.

•Print—Prints the current panel. We recommend landscape page orientation when printing rules. If ASDM is running in Netscape Communicator and the user has not yet granted print privileges to the Java applet, a security dialog appears requesting Print privileges. Click Grant to grant the applet printing privileges. When using Internet Explorer, permission to print is already granted when you originally accepted the signed applet.

•Clear ASDM Cache—Clears the local ASDM images. ASDM downloads an image locally when you connect to ASDM.

•Clear Internal Log Buffer—Clears the system log message buffer.

•Exit—Exits ASDM.

Reset Device to the Factory Default Configuration

The default configuration includes the minimum commands required to connect to the security appliance using ASDM. This feature is available only for routed firewall mode; transparent mode does not support IP addresses for interfaces, and setting the interface IP address is one of the actions this feature takes. This feature is also only available in single context mode; a security appliance with a cleared configuration does not have any defined contexts to automatically configure using this feature.

This feature clears the current running configuration and then configures several commands. The configured interface depends on your platform. For a platform with a dedicated management interface, the interface is named "management." For other platforms, the configured interface is Ethernet 1 and named "inside."

The following commands apply to the dedicated management interface, Management 0/0 (for a platform without a dedicated management interface, the interface is Ethernet 1):

interface management 0/0

ip address 192.168.1.1 255.255.255.0

nameif management

security-level 100

no shutdown

asdm logging informational 100

asdm history enable

http server enable

http 192.168.1.0 255.255.255.0 management

dhcpd address 192.168.1.2-192.168.1.254 management

dhcpd lease 3600

dhcpd ping_timeout 750

dhcpd enable management

If you set the IP address in this dialog box, then the http command uses the subnet you specify. Similarly, the dhcpd address command range consists of addresses within the subnet that you specify.

After you restore the factory default configuration, save it to internal Flash memory using the File > Save Running Configuration to Flash item. This menu item saves the running configuration to the default location for the startup configuration, even if you previously configured the Boot Image/Configuration to set a different location; when the configuration was cleared, this path was also cleared.

Note This command also clears the Add Boot Image configuration, if present, along with the rest of the configuration. The Add Boot Image pane lets you boot from a specific image, including an image on the external Flash memory card. The next time you reload the security appliance after restoring the factory configuration, it boots from the first image in internal Flash memory; if you do not have an image in internal Flash memory, the security appliance does not boot.

Fields

•Use this address for the "Interface_ID" interface which will be named as "name"—Manually sets the IP address of the management interface, instead of using the default address, 192.168.1.1. For a platform with a dedicated management interface, the interface is named "management." For other platforms, the configured interface is Ethernet 1 and named "inside."

•Management IP Address—Sets the management interface IP address.

•Management subnet mask—Sets the subnet mask of the interface. If you do not set a mask, the security appliance uses the mask appropriate for the IP address class.

Packet Tracer

The tool provides detailed information about the packets and how they are processed by the security appliance. In the instance that a command from the configuration did not cause the packet to drop, the packet tracer tool will provide information about the cause in an easily readable manner. For example if a packet was dropped because of an invalid header validation, a message is displayed that says, "packet dropped due to bad ip header (reason)."

In addition to capturing packets, it is possible to trace the lifespan of a packet through the security appliance to see if it is behaving as expected. The packet tracer tool lets you do the following:

•Debug all packet drops in production network.

•Verify the configuration is working as intended.

•Show all rules applicable to a packet along with the CLI lines which caused the rule addition.

•Show a time line of packet changes in a data path.

•Inject tracer packets into the data path.

Fields

•Interface—Specifies the source interface for the packet trace.

•Packet type—Specifies the protocol type for the packet trace. Available protocol types are icmp, rawip, tcp or udp.

–Source IP—Specifies the source address for the packet trace.

–Source Port—Specifies the source port for the packet trace.

–Destination IP —Specifies the destination address for the packet trace.

–Destination Port—Specifies the destination port for the packet trace.

Ping

The Ping dialog box provides a useful tool for verifying the configuration and operation of the security appliance and surrounding communications links, as well as basic testing of other network devices.

A ping is the network equivalent of sonar for submarines. A ping is sent to an IP address and it returns an echo, or reply. This simple process enables network devices to discover, identify, and test each other.

The Ping tool uses ICMP described in RFC-777 and RFC-792. ICMP defines an echo and echo reply transaction between two network devices, which has become known as a ping. The echo (request) packet is sent to the IP address of a network device. The receiving device reverses the source and destination address and sends the packet back as the echo reply.

Using the Ping Tool

Administrators can use the ASDM Ping tool as an interactive diagnostic aid in several ways, for example:

•Loopback testing of two interfaces—A ping may be initiated from one interface to another on the same security appliance, as an external loopback test to verify basic "up" status and operation of each interface.

•Pinging to an security appliance interface—An interface on another security appliance may be pinged by the Ping tool or another source to verify that it is up and responding.

•Pinging through an security appliance—Ping packets originating from the Ping tool may pass through an intermediate security appliance on their way to a device. The echo packets will also pass through two of its interfaces as they return. This procedure can be used to perform a basic test of the interfaces, operation, and response time of the intermediate unit.

•Pinging to test questionable operation of a network device—A ping may be initiated from an security appliance interface to a network device that is suspected to be functioning improperly. If the interface is configured properly and an echo is not received, there may be problems with the device.

•Pinging to test intermediate communications—A ping may be initiated from an security appliance interface to a network device which is known to be functioning properly and returning echo requests. If the echo is received, the proper operation of any intermediate devices and physical connectivity is confirmed.

Troubleshooting the Ping Tool

When pings fail to receive an echo, it may be the result of a configuration or operational error in a security appliance, and not always due to "NO response" from the IP address being pinged. Before using the Ping tool to ping from, to or through an security appliance interface, verify the following:

•Verify that devices in the intermediate communications path, such as switches or routers, are properly delivering other types of network traffic.

•Make sure that traffic of other types from "known good" sources is being passed. Use Monitoring > Interface Graphs.

Pinging from an security appliance interface

For basic testing of an interface, a ping may be initiated from an security appliance interface to a network device which, by other means, is known to be functioning properly and returning echoes via the intermediate communications path.

•Verify receipt of the ping from the security appliance interface by the "known good" device. If it is not received, there may be a problem with the transmit hardware or configuration of the interface.

•If the security appliance interface is configured properly and it does not receive an echo from the "known good" device, there may be problems with the interface hardware receive function. If a different interface with "known good" receive capability can receive an echo after pinging the same "known good" device, the hardware receive problem of the first interface is confirmed.

Pinging to an security appliance interface

When attempting to ping to an security appliance interface, verify that pinging response (ICMP echo reply), is enabled for that interface in the Configuration > Properties > Administration > ICMP panel. When pinging is disabled, the security appliance cannot be detected by other devices or software applications, and will not respond to the ASDM Ping tool.

Pinging through the security appliance

•First, verify that other types of network traffic from "known good" sources is being passed through through the security appliance. Use Monitoring > Interface Graphs, or an SNMP management station.

Note If a host name has been assigned in the Configuration > Network Objects/Groups pane, you can use the host name in place of the IP address.

•Interface—(Optional). The security appliance interface that transmits the echo request packets is specified. If it is not specified, the security appliance checks the routing table to find the destination address and uses the required interface.

•Ping Output—The result of the ping. When you click Ping, three attempts are made to ping the IP address, and three results display the following fields:

–Reply IP address/Device name—The IP address of the device pinged or a device name, if available. The name of the device, if assigned as a Network Object, may be displayed, even if NO response is the result.

–Response time/timeout (ms)—When the ping is transmitted, a millisecond timer starts with a specified maximum, or timeout value. This is useful for testing the relative response times of different routes or activity levels, for example.

•Ping—Sends an ICMP echo request packet from the specified or default interface to the specified IP address and starts the response timer.

•Clear Screen—Clears the output on the screen from previous ping command attempts.

Traceroute

The Traceroute dialog box provides a useful tool to determine the route packets will take to their destination.

Traceroute Output

The traceroute tool prints the result of each probe sent. Every line of output corresponds to a TTL value in increasing order. The following are the output symbols printed by the traceroute tool:

Output Symbol

Description

*

No response was received for the probe within the timeout period.

nn msec

For each node, the round-trip time (in milliseconds) for the specified number of probes.

!N.

ICMP network unreachable.

!H

ICMP host unreachable.

!P

ICMP protocol unreachable.

!A

ICMP administratively prohibited.

?

Unknown ICMP error.

Fields

•Hostname or IP address—Specifies the hostname of the host to which the route is traced. If the hostname is specified, define it with Configuration > Global Objects/Groups, or configure a DNS server to enable traceroute to resolve the hostname to an IP address.

•Timeout—Specifies the amount of time in seconds to wait for a response before the connection times out. The default is three seconds.

•Port—Specifies the destination port used by the UDP probe messages. The default is 33434.

•Probe—Specifies the number of probes to be sent at each TTL level. The default count is 3.

•Min & Max TTL—Specifies the minimum and maximum time to live values for the first probes. The minimum default is one, but it can be set to a higher value to suppress the display of known hops. The maximum default is 30. The tool terminates when the traceroute packet reaches the destination or when the maximum value is reached.

•Destination Port—Specifies the destination port used by the UDP probe messages. The default is 33434.

•Specify Source Interface or IP Address—Specifies the source interface or IP address for the packet trace. This IP address must be the IP address of one of the interfaces. In transparent mode, it must be the management IP address of the security appliance.

•Reverse Resolve—When checked, the output displays the names of hops encountered if name resolution is configured . If left unchecked, the output displays IP addresses.

•Use ICMP—Specifies the use of ICMP probe packets instead of UDP probe packets.

•Traceroute Output—Displays detailed messages about the traceroute.

•Traceroute—Starts the traceroute.
